. WEED-CUTTING- IMPLEMENT.

Application-filed March 4, 1914. Serial No. 822,540.

To all whom it may concern:

Beit known that I, CHARLES E. DOUGLAS, a citizen of the United States,and a resident of Turner, in the county of Marion, State of Oregon, haveinvented, anew and useful Improvement in Weed-Cutting Implements, ofwhich the following is a specificat1on.

My invention relates to improvements in weed-cutting implements ordevices. 7

In certain localities the rapid growth of weeds is a source of greatannoyance to the farmer, and in some localities these weeds spring up infreshly plowed land so fast that it is impossible for the farmer toproceed with his subsequent work of cultivation. It has been discoveredthat the cutting of these weeds above the surface only acts as astimulant to their further growth, but when out close to their rootsthey will die.

One of the objects of my lnvention 15,

therefore, to provide a simple, durable dc vice adapted for cutting theweeds beneath the surface of the soil.

My invention comprises a cutter blade suspended from a vehicle body bymeans permitting the cutter blade to be raised and lowered relatively tothe depth at which the cutting is done.

My invention further includes a novel and beneficial feature with regardto taking care of the strain on the cutter blade when at work.

Other novel features of my invention are hereinafter fully described.

In the accompanying drawings: Figure 1 is a side elevation of myimplement with the right forward wheel removed; Fig. 2 is a transversesection taken approximately on the line 22 of Fig. 1; and Fig. 3' is aover by the floor 6. The body is mounted on the rear wheels, 0, and thefront wheels 6; the front wheel axle 6 being rotatable about theking-pin f. A tongue 9 is connected to the axle e by hooks and eyes 9 inthe usual way. Located beneath the tongue 9 is a Z-shaped metal arm 72.which forms a bearing for the whifile trees 72 and at the rear end ofthe tongue g is a downwardly projecting hook h. g V

Fastened on the bottom of the sills, a, are journal boxes, i, in whichare journaled the transverse crank shafts j formed with a Specificationof Letters Batent.

7 middle crank-portion j" and crank arms j The crank-arms 7" at theirextremities. support the weed cutting device. This consists of a framecomprising a series of cross beams m, on which are fastened thesupporting elements or hangers, t, on the lower ends of which isfastened the cutter blade 8. See Fig.2., The cutterbladeispreferablyarranged angular or V-shaped. See Fig. 3. The cutter blade 8 is furtherpreferably upturned at the back, as indicated at s in Fig. 2. The bladeis riveted to the lower outturned'portions t of the hangers t. The crankarms 1' of the crank shafts j bear in the journal boxes is mounted onthe cross beams m; and the middle crank portions j of the crank shafts jare connected by a bar 91.. For convenience of assembling I make the barat of two parts n, M, provided with knuckle portions 41. constitutingjournalbearings for said middlecrank portions j of the crank shafts j.Bolts n clamp the parts 12., n firmly together. The top part n is madewith vertically projecting ears 0. to which the lever 39 is rotatablyconnected by a pin 0.

On the floor 6 is mounted a quadrant and lever 6 p, the floor beingprovided with a slot 6 to accommodate the lever p. A pivot pin 1",carried between the sills, a, forms fulcrum for the lever p. The latterhas the usual pawl p controlled by a spring 39. The drivers seat I)? islocated convenient to the lever 19. i

Located near the vertex of the cutting blade .9 is a hook s and a chain8 is connected with this hook and the hook on the it is desired torai'se'the cutter blade 8, the

lever 10 may be released and thrown backward; the movement of the leverp being communicated through the medium of the bar 01 tothe crank shaftsj and causes the latter to rotate in unison, thereby lifting or loweringthecutterblade s so as to clear or out under the ground.

I claim: 7 1. In an implementof the character described, the combinationof a plurality of crank shafts having crank elements at their elements,and means for moving said bar longitudinally.

2. In an implement of the character described. the combination of aplurality of crank shafts having crankelements at their extremities: andintermediate the latter, supporting elements pendent from theextre1nities of the crank shafts the lower" ends of said supportingelements bent horizontally, transverse bracing elements connecting thesupporting elements in pairs, a bar connecting the intermediate crankelements of said crank shafts, a Vshaped cutter-blade fastened to. thelower ends of the supporting elements, the back of the cutter bladebeing turned up, and: a lever attached to said bar, a notched quadrantand locking means engaging therewith carried by the lever.
